IMPROVED MACHINE FOR SCOURING .AIVD SETTING OUT LEATHER The Schedulereferred to in these4 Letters Patent nd making part 0f the same.,

To aZ persons to whom these presents may come Be tikuown that I, CHARLESHOLMES, of Boston, 1n the county of Su'olk, and State of Massachusetts,

I have invented a new and useful Improvement in Machinery for Scouringand Setting Out Leather; and I c do hereby declare the same to be fullydescribed in the following speciiication, and represented in theaccompanying drawings, of which- Figure 1 is a top View, Figure 2, aside elevation, Figure 3, a vertical and longitudinal section, andFigure 4, an end elevation of a scouringcarriage,

and its mechanism, as-improved by me.

said tool-carriers, and holding such up, so that it or they may notoperate on the leather while the reciprocating carriage may be inmovement over the same.

Also, in the arrangement of buffers, or dampers, with the tool-carrierlifter-rods, and the rocker-plate.

Also, in the arrangement and combination of gutters, 0r the same and adrip-trough, or pan, with lower guides of the reciprocating carriage.

In the drawings- A denotes the said reciprocating carriage, which isusually supported by two -parallel and horizontal ways, or rails, thatgo between parallel guides, a a, b b, extended from the sides and upperpart of the said carriage, in manner as represented in the drawings. Asthe surfaces in contact of these guides and rails have to be kept welloiled, to prevent friction and wear, the lubricating-duid is liable togather on the ends of the lower guides, and drop therefrom upon theleather while being operated on by the tools, and thereby blacken orotherwise injure it.

In order to prevent such falling of the oil on the leather or table ofthe machine, as the case may be, I apply to each end of each lower guideb, an inclined gutter, or channel, c, and arrange, directly underneathits lowermost or outer end, a trough, or long shallow drip-pan, orreservoir, B, which should be fixed either to the carriage or theslide-bar on which it rests, it being arranged so that the surplus, orwaste oil received inio the guttersshall, after passing through them, bedischarged into and caught by such reservoir.

The tool-carriers, at one endrof the carriage, are

shown at C O', each being pivoted upon a rod, d, extending transverselythrough the carriage, or from one to the other of the side plates e ethereof.

The lifter-rods of the said tool-carriers are shown at ff, they beingextended'through long` slots in the rocker-plate D, which goes throughthe carriage, and is pivoted to the middle thereof, so as to turn on aor head, y, between which and the vplate is an elastic block, h, ofIndia rubber, which constitutes a buffer for the plate to strikeagainst, in order to lift the toolcarrier. lhis elastic buffer preventsthe jar and noise which are incident to the inelastic pin, or shoulderordinarily employed 0n the lifter-rod.

On the upper part of each lifter-rod, a male screw, t, is formed. Itscrews up into a block, E, hinged to an arm, F, which at its' inner endis pivoted to the carriage A, the whole being arranged as represented.

By removing the pivot-pin 7c from the arm, such arm may be raised frombetween its back supports, l l,and used as a lever to turn the block Earound upon the screw i, in order to effect the requisite verticaladjustment of the tool-carrier.

It has been found, when the screw t' has been passed through the blockwithout being screwed into it,l and was held to it by nuts screwed .uponthe screw, that such nuts, with check-nuts, soon work loose, owing tothe constant jar to which they are subjected while the machine was inuse.

Withmy improvement, the adjustment of the toollcarrier being onceeffected, it cannot become disturbed, except the arm be first removedfrompivot-pin and of the side-bar, and also through the arms and the topof the carriage.

The bar is arranged between parallel guides, m m, and has an arm, n,extended from it, at a right angle, and 'at-its front end.

A rod, or pitman, o, projecting from the said arm, in manner as shown,and going through a standard, p, is hinged to one end'of a handle, q,there being at the opposite end of such handle another suchconnectingrod, which is to project from the notched slide of anotherseries lof arms, F, which is to be supposed to be applied tothe-carriage A, and to be employed in supporting another set oftool-carriers.

By laying hold of and moving the handle, an attendant may so move andadjust either or both of the slide-bars G as to cause either or each ofsuch bars to hold in a raised position either or all of thetool-carriers beneath it; that is to say, such tool-carrier, or carriersmay be so raised for thepurpose of keeping its tool or their tools outof action on the leather, while the carriage may be in movement over it.v

In the drawings- R denotes the rod on which the tool-carrier springs aresupported. This rod is supported, at its ends, by two blocks', S S,which are arranged in vertical guideslots in the side-plates of thecarriage A. Screws, 'l T, are screwed into each of these blocks, theprismatic heads r r, of these screws, being arranged directly underneatha shelf, q, projecting from the earriage.

Heretofore it has been customaryto screw the screws down through. theshelf and against the block S, but when theoil-catching receptacle B isapplied, either to the carriage or slide, it becomes, under suchcircumstances, in the way, so as to prevent the screws from being easilygot at'for the purpose of being revolved. By arranging the screw-headsunderneath, and so as to abut against the shelf, access to them may beeasily had at any time, to better advantage than is the case when theyare over the shelf.

rod o, and the notched slide-bar G, arranged, connected, and applied tothe'carriage, and to the series of arms F F, of the lifter-rods,substantially as specified.

l also claim the combination and arrangement of the vsponts, or guttersc, and the oil-receive;k B, with the lower carriage-guidesb b.

I also claim the combination of the buffers, or dampers h, with thetool-carrier lifter-rods f, and the rockerplate l).

' I also claim, when the spouts anddrip-pan are eniployed with the lowerguides of the carriage, as described, the arrangements of the heads ofthe screws T T beneath and against the shelf q', such being as and forthe purpose set forth.

CHARLES HOLMES.
